The ratio for the percent increase has a smaller denominator than the percent decrease.

Step-by-step explanation:

From 45 to 75, the increase is 30

If we check the % increased, (30/45)*100 = 66.667%

If we decrease the price from 75 to 45, the amount is same, i.e. 30 but the denominator is changed.

(30/75)*100 = 40%
